What is different of the 3D Obsidian ALR and the normally Obsidian ALR?
VIVIDSTORM always want to offer the best choice for different projector's request;
If your projector has low lumens, use a projector with a long throw or standard throw;
But want to watch the screen under low light conditions;
Because we have 3D Obsidian ALR and the normally Obsidian ALR screen material can be choice,it will make confuse when you purchase it before;
We suggest that you can choose the screen material that suits you through the video:
Summarize:
Please remember that there are falsely labeled lumens indicators on the market, so please refer to ANSI lumens as the standard reference value;
A: If the ANSI lumens of your projector is lower than 1800, we suggest you choose 1.2 gain 3D Obsidian ALR screen material
B: If the ANSI lumens of your projector is higher than 1800, we suggest you choose 0.8 gain the normally Obsidian ALR screen material

Shouldn’t you also consider screen size in addition to projector brightness? For example, 1000-1500 lumens on a 100" diagonal screen is quite bright (100-150 nits), while on a 140" screen it’s much reduced (50-80 nits).
My specific situation: should I pick 3D Obsidian ALR or Normal Obsidian ALR for a 100" diagonal image, with a 1000 lumen (calibrated, not spec’d) projector, in a room that is completely dark however it has light colored walls and a white ceiling that reflects a lot of light back to the screen?
